In a recent interview with Metro, the director reveals that he wants to cast Tom Hardy and Chris Pine in his movie. I think both of these actors would be a perfect fit for the film. When talking about Hardy, Stefano said:
"I mean, I like almost everything [he’s been in]. I’m waiting for his Venom. Even in Mad Max, he was great."
He then went on to talk about Pine and what he could bring to the movie:
"He’s tough, but he’s smart and he can have a sense of humour but he can [also] be in such a dramatic role.
